I see every ones posts and you all talk about Protein drinks and cottage cheese and more. My Dr. says only skim milk broth sugar free Popsicle,Jello ,No Protein shakes ! just tea and thin liquids. Has anyone else had to do this? Oh and I have to do it for 21 days. I just don't know if this is possible ? My weight is 255 and my goal is 165. Please if you had to do this tell me how I can get past this.
